Figure 1: Landmarks and Lines used in the study. Trichion (T) - Where the flat portion of the forehead from glabella meets the hairline; glabella (G) - inferior most point on the fore head; Line "FFA" - Facial Axis line of Forehead-Line joining Trichion and the Glabella; Point "FFA" - Midpoint on the perpendicular bisector of the line "FFA"; point "FA" - Facial axis point of maxillary incisor (labial most point on maxillary incisor); GALL - Goal Anterior Limit Line is drawn parallel to the head's frontal plane (FPH). It passes though the line "FFA" and tangent to the point FFA. Ideally, this line should also pass through the point "FA" (facial axis point of the maxillary central incisor). GALL line indicates the ideal anteroposterior position of maxillary incisor in relation to forehead
